Unable to View Updated Model with Same Name in Autodesk Platform Services (APS) Viewer

I am uploading a STEP file to an Autodesk Platform Services (APS) bucket and translating it to SVF for viewing in the APS Viewer.

Later, I want to upload a different model with the same name. To achieve this, I:

Deleted the manifest of the original model using the API:
developer.api.autodesk.com/modelderivative/v2/designdata/{urn}/manifest
Deleted the model itself using the API:
developer.api.autodesk.com/oss/v2/buckets/:bucketKey/objects/:objectKey
Uploaded a new model with the same name.

The new model is successfully uploaded and translated, but it does not appear in the Viewer.

I am using the Visual Studio Code extension for uploading and translating the model. Can anyone help me understand why the new model is not visible in the Viewer and how I can fix this issue?

Thanks in advance for your help!
